The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$3 x = 9 y + 7$$
Divide both parts of the equation by 3
We get the answer: x = 7/3 + 3*y
3*x-9*y = 7
Looking for similar summands in the left part:
-9*y + 3*x = 7
Move the summands with the other variables
from left part to right part, we given:
$$3 x = 9 y + 7$$
Divide both parts of the equation by 3
x = 7 + 9*y / (3)
We get the answer: x = 7/3 + 3*y
Rapid solution

x1 = 7/3 + 3*re(y) + 3*I*im(y)
$$x_{1} = 3 \operatorname{re}{\left(y\right)} + 3 i \operatorname{im}{\left(y\right)} + \frac{7}{3}$$
x1 = 3*re(y) + 3*i*im(y) + 7/3
